Background: Diabetic retinopathy is a common microvascular complication of both type 1 and type 2
diabetes mellitus. If left untreated, it can progress to serious visual disability. Coexistence of
hypertension with diabetes has been described as another risk factor adding to the problem. We
designed this study to assess the occurrence of diabetic retinopathy in hypertensive diabetic patients of
this region and to compare it with normotensive diabetic patients. Methods: This cross-sectional study
was carried out on 200 previously diagnosed diabetic patients. Apart from routine examination and
investigations, retinopathy and blood pressure assessment of each patient was done using standard
techniques. Hypertensive diabetic subjects (Group-I, n=107) were compared with non-hypertensive
diabetics (Group-II, n=93) for the presence of retinopathy. Results: Retinopathy and hypertension were
observed in 51% and 53.5% of the total diabetic patients respectively. Hypertensive diabetic patients
had significantly higher percentage of retinopathy compared to non-hypertensive diabetic patients (58
vs 43%; p<0.05). Conclusion: Retinopathy and hypertension are highly prevalent in our diabetic
patients. The proportion of retinopathy is significantly more in hypertensive as compared to
normotensive diabetics.
